The present Application is based on International Application No. PCT/JP2003/013270, filed on Oct. 16, 2003, entitled “Hair Fiber Mounting Method”, which in turn corresponds to Japanese Application JP 2002-349225 filed on Nov. 29, 2002, and priority is hereby claimed under 35 USC §119 based on these applications. Each of these applications are hereby incorporated by reference in their entirety into this application.
1. Field of the Invention
This invention relates to a hair-fiber mounting method, in particular to a method of forming a desired hairstyle by attaching hair fibers to a person's natural hair.
2. Description of the Related Art
A desired hairstyle can be realized by making a person's hair look longer by attaching hair fibers to the person's natural hair. This technique is called “hair extension,” and it has been disclosed in Japanese Patent No. 3338433.
Briefly, a hair-extension technique includes the following steps: (1) a hair-extension bundle (fiber bundles) and a bundle of natural hair (natural-hair bundle) are crossed with each other, (2) the loose part of the natural-hair bundle is wound around the both parts of the fiber bundle that has been bent into two halves at its middle, (3) the fiber bundle is moved towards the person's scalp by pulling the natural-hair bundle, (4) both halves of the fiber bundles are braided with the loose part of the natural-hair bundle so as to form a braided part, and (5) the braided part is fixed by being partially thermal-fused or bound with elastic threads.
As the material for the hair bundle, burn-resistant polyethylene-based synthetic fibers or the like are selected because of the soft tactile sensation that they provide. However, this extension technique has not been applied to a person's entire head, and therefore a method for applying the hair-extension to all of a person's head is still desired.
Japanese Published Utility Model Application No. 5-27016 has disclosed another hair-extension method. With this method, plural ring-shaped fringe members are provided and connected with each other by plural connection members that extend longitudinally an appropriate distance. The fringe members are formed so as to include elastic members at least at their middle part lengthwise—and some artificial hairs are interwoven with the fringe members. The fringe members are affixed to the natural head hair by connection members, and the person's natural hair is pulled out from the fringe members. However, due to the use of the ring-shaped fringe members, this method has the disadvantage that the hair extension looks unnatural.
The current invention aims at developing a method of attaching fibers (namely, hair extension) to either all or a part—depending on the hairstyle—of person's natural head-hair in a short time, while maintaining a natural-looking hair style.
To achieve the above-mentioned goal, this invention involves a hair-fiber mounting method wherein fiber bundles consisting of plural fibers are braided with natural-hair bundles that are formed by selecting and bundling plural natural head-hairs, and wherein the loose part of the natural-hair bundle (i.e., the part that is not attached to the scalp) and two halves of the fiber bundles are hung together from the braided portions. This method includes:
Each of the natural-hair bundles is formed by binding a greater volume of the hair on the upper side of the person's head than on the lower side of the person's head, and in such a way that each selected portion of the natural hair forms an upside-down triangle.
By the method of the present invention, fibers can be attached to the natural hairs in a short time so that the resulting hair extension looks natural.
Embodiments of this invention will now be described while referring to the aforementioned drawings.
The method of forming the joined-hair bundle includes: a natural-hair bundle 2 and a fiber bundle 7 with predetermined length are crossed with each other roughly in the center of the fiber bundle 7 (the crossing of the natural-hair bundle 2 and the fiber bundle 7 may be made either near to the right end or to the left end of the fiber bundle 7); and in this case, the natural-hair bundle hangs down, crossing the horizontally placed fiber bundle 7, and then, the loose part of the natural-hair bundle 2 is wound on the left and on the right of the crossing portion at least once respectively. This process is referred to as a winding process. This winding process is to form a loop 5 at the crossing portion by winding the natural-hair bundle 2 once around on the right (left) of the fiber bundle 7, and then by winding the natural-hair bundle 2 once around on the left (right) of the fiber bundle 7 successively. At this stage, the loose part of the natural-hair bundle 2 hangs down, and furthermore, two halves (end-parts) of the fiber bundle 7 with pre-determined length hang down from the point of the loop 5. Then, the loose part of the natural-hair bundle 2 and the two halves (end-parts) of the fiber bundle 7 are braided near at the crossing portion, being linked to the loop 5, so as to bind the natural-hair bundle 2 with the fiber bundle 7.
The braided portion 6 is fixed by winding a separated portion of the fiber bundle 7 around the braided portion 6.
In the meantime, the braided portion 6 is formed by braiding three end-parts, i.e., the two halves (end-parts) of the fiber bundle 7 with a loose part of the natural-hair bundle 2. Also, the braided portion 6 may be fixed by winding and binding an elastic thread 11 around the joined hair bundle several times (5 to 7 times).
As can be seen in
Also, as appropriate, a part of the fiber bundle 7 can also be thermally fused to fix the braided portion 6. But it is better to use elastic thread 11 in order to avoid the risk of burning caused by the thermal-fusion. Another benefit of using elastic thread 11 is that an fiber bundle 7 that has been attached can be easily removed simply by cutting the elastic thread 11.
The extensions are formed so as to cover the entire head. Some hairs of the extended portion can be cut, depending on the hairstyle,.
The hairstyle shown in
This invention has benefits as described below.
The method of this invention includes
With this invention, hair-extension can be carried out in a short time while maintaining a natural-looking appearance.
A greater volume of hair is selected at the upper side of the head than at the lower side, and the part of each natural-hair bundle that is between the scalp and the bundles-joining area is longer than the part below the bundles-joining area.
With this invention, the burden on the scalp can be minimized.
Further, each joined-hair bundle is placed at an upper part between the two adjacent lower joined-hair bundles, in other words that the joined-hair bundles along a line do not overlap the joined-hair bundles along the immediately below line.
With this invention, the natural appearance of the hair is improved.
